A component required a bean named 'userService' that could not be found.

创建springboot+dubbo在服务端

@Service
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;

    @Override
    public List getAll() {
        List users = userMapper.selectAll();
        System.out.println(users);
        return users;
    }
}

启动就报错

Description:


A component required a bean named 'userService' that could not be found.




Action:


Consider defining a bean named 'userService' in your configuration.

配置文件不管怎么改都不行，后来在@service后面添加("userService")后服务正常运行

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;

    @Override
    public List getAll() {
        List users = userMapper.selectAll();
        System.out.println(users);
        return users;
    }
}

如果对你有帮助的话请扣个1，谢谢
